Three instrumentals there are, as usual.
Three quite melancholic moments. Time goes by, people grow up, ...
The first ('Ricky' in the title is The author's son) and the second composition (glancing at a magazine Renato read the name 'Wilson' and he immediately associated it with the will power of his own son. Then that name became 'WillSon' in his mind) are strongly related with the inner feelings of a father facing the unstoppable flowing of life.
The third one is probably a moment of reflexion. The title is a play on words, between Italian and English. The correct English pronounce of 'China' is just alike an italian dialect question that means 'Do you have....?'. So the title could be 'Do you have a cigarette ?', if you can understand the italian colloquial talk.
It is also dedicated to a well known and well liked homeless that used to live in the streets of Ancona, always asking cigarettes to passers-by . Many years ago he died, everyone remembers him with affection anyway.
